Description Write a program that finds and displays all pairs of 5-digit numbers that between them use the digits 0 through 9 once each, such that the first number divided by the second is equal to an integer N, where . That is, abcde / fghij =N wh…
[题意]:输入正整数n,用0~9这10个数字不重复组成两个五位数abcde和fghij,使得abcde/fghij的商为n,按顺序输出所有结果.如果没有找到则输出“There are no solutions for N.”.这里2<=n<=79. [分析]: 1.因为n>=2,且abcde=fghij×n,满足abcde>fghij.若a=0,则fghij的最小值为12345,abcde<fghij,矛盾.所以a≠0. 2.因为a≠0,所以12345<=abcde&l…
